This invention'relates to devices for scoring, creasing and indenting paper sheets preparatory to folding and more particularly to devices inthe form of attachments .to

machines for shearing and cutting paper,-

[such machines consisting of a' base having a 7 platform for the paper, a power, driven shear A further featureis to provide'a plurality ofscoring blades,- some with two or more op; erative edges, or combinations of scoring blades, perforating devices and cutting knives, all being readily attachable to the binder beam, in a manner permitting easy and instant change, as maybe desired.

These and like objects are accomplished by the novel and practical construction and arrangement of-parts hereinafter described and shown in .theannexed drawing,f orming a material part of this. disclosure, and; in which 4 f Figure 1 is a transverse sectional View taken in a vertical plane through a conventional type of paper cutting machine and illustrating the application of an embodiment I c with relation to the chains 24, are attached of the invention.

Referring more in detail to the drawing, the numeral 10 designates in general a hollow cabinet base, such as is customary for paper cutting machines, the mechanism being partially disposed therein; I

A projecting shelf-like platform 11 at the front contains a rectangular recess extending lengthwise from side to side, th e'same being receptive of an elongated block 12 of wood I or other'material of a nature not liable to damage the knives or scoring blades which may be brought in contact with it, theblock being reversible to permit all four sides to be j used and may be readily replaced by another when worn. I l I I The upper part of the machine .is open at the top and disposed therein are uprights 13 connected by a bar l l'carrying a series ,of vertical guides 15, these guides being suited to enter into corresponding slots 16 formed in a cross Jbinder 17 adapted to clamp the paper sheets upon the platform.

Movable across the face of the binder bar 17 is a power operated knife bar 18 carrying a shear blade 19 and guided at the front by uprights 20 at the'ends, the same being positioned above the platform side guides 21.

Mounted in the upper portions of the up:

, rights-13is a shaft-.22 having near'its ends plate segments 23 .over which are trained flexible elements24, such as chains, the same engaging the 'binderbar 17 near its upper edge, one end of the'chains being fixed to the'segments.

Coiled springs 25, fixed respectivelyjto the shaft 22 and segments, operate tofmaintain the bar 17 in a normally raised position.

.Another pair of chains 26, secured to the" opposite ends of the segments, and offset at their oppositeends to br'ackets27 reach ing up from the'binderbar' 17j so that "the same is substantially counterbalanced by the H action ofthe springs 25. J

Extending down from oneend of the bar I and provided with a forwardly extending arm 30 carrying at its end a pivot31.

The pivot is freely engaged in a slot 32 in theend of a link33, in turn pivoted to a foot lever 34 fulcrumed on a stud 35 set in a bracket 38 at the front of the base, thefoot lever being normally raised by the action of a spring 37 coiled around the stud. Y

;All of the several parts described in the foregoing are. elements of a conventional paper cuttlng machine and in themselves constitute no part of the present invention but are given in order to arrive at a complete understanding thereof.

The invention is composed. of an angle bar 46 41 having one on both at its longi held by either of its an tudinal edges beveled toprod'ucea creasing or scoring effect upon paper, this bar being gles againstthe lower surface of the binder bar 17.

The clamping means consists of a narrow flat plate 42, equal in width torthe" binder bar 17 and having fixed therein two or more their inner edges against the guides 15 and rods 43 suited to pass through appropriate vertical openings in the binder bar and, theresecured by wing nuts 44:. 1

Obviously by slackening the nuts, the plate 4&2 may be relaxed, permitting withdrawal or substitutionof other scoring bars, such for instance as indicated in Figure 4, in which a three limbed angle is shown, respecti'vely 45, 46 and 47. i s

As shown in Figures 6 and 7, a combined scoring and shearing cutter is disclosed, the

the portion to be creased arranged to register over the wooden block12.

Such sheet is shown in detail in Figure 5,. known as tympan paperand is scored, as at 56, to readily permit bending. as desired.

It is to be understood that in operation, the

paper sheets having been adjusted, the crease is formed by depression of the foot lever 34, causing the scoring beanr to descend with Whatever force be necessary. i

In addition .'to the foregoing, other typesof paper cutting and perforating dies, may be substituted, as for instance that shown in. Figure 8 in which a platen?) may be clamped to the binder by the element 42,-said plate having a row 0t perforated pins 54 extending downward near its outer edge, the

pins entering adie having conformable openings disposed in place of the block 12, and it Will be obvious that dies of other shape may be substituted.

As changes of construction could be made Within-thescope of the invention, it is intended that all matter contained in the foregoing description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is s 1. In combination with a paper cutting. machine having a platform and a foot operated binder bar thereove-r, of an angle bar having one or more scoring edges, and means to clamp the bar to said binder bar.

2. In combination with a paper cutting machine having a platform, paper guides at its rear and a foot lever actuated binder bar, of a scoring blade, and means to adjustably secure said blade to the lower surface of said binder bar.

3. In combination with a paper cutting machine having a platform and a binder bar movable thereover, of means for cutting,

two or more scoring edges disposed at right angles one to another, and means to a'liix said bar to said binder bar in such manner asto' extend one of its edges selectively downward. 1 k V i a V 5. In combination with a paper cutting machine having a platform containing a longitudinal recess, a footoper'ated binder bar and means to normally raise said bar, of a wooden block reversibly engaged inthe recess, a creasing bar having a right angled element, and a clamp plate to hold said element in rigid relation with the, under edge of saidba-rL g p 7 In testimony whereof I atlix my signature.
